 * Note that, due to trying to use names similar to the protocol specifications,
 * there are many mixed case field names in the structures below.  Although
 * this does not match typical Linux kernel style, it is necessary to be
 * be able to match against the protocol specfication.
 *
 * SMB2 commands
 * Some commands have minimal (wct=0,bcc=0), or uninteresting, responses
 * (ie no useful data other than the SMB error code itself) and are marked such.
 * Knowing this helps avoid response buffer allocations and copy in some cases.
